Internal Funds Allocation and the Ownership Structure: Evidence from Korean Business Groups

We examine the relationship between the controlling shareholder’s cash flow rights and the funds transfer in the internal capital market within Korean business groups (chaebols) during the period from 1998 to 2001. We find that the funds allocation in the firms where controlling shareholders have high cash flow rights is better aligned with the investment opportunities and therefore, more efficient than in the firms where they have low cash flow rights. This effect is stronger when they have controlling powers large enough to expropriate minority shareholders. However, during the financial crisis period, funds simply move toward the firms where controlling shareholders have high cash flow rights. The results evidence the tunneling behavior in the internal capital market within a chaebol that the ownership structure distorts the allocation of internal funds in such a way as to benefit the controlling shareholders.JEL Classification: G31, G30     

An Empirical Examination of the Parimutuel Sports Lottery Market versus the Bookmaker Market

A sports lottery in Korea presents a unique opportunity for comparing a parimutuel‐type sports lottery market against a bookmaker market outside the realm of horse racing. Using two‐ and three‐game soccer final‐score betting in the sports lottery market in Korea, which features matches in the English Premier League, we compare winning payoffs in this parimutuel‐type sports lottery against corresponding payoffs from an established bookmaker market in the United Kingdom. We find that for outcomes with relatively high payouts (that is, lower‐probability events), winning bets placed in the sports lottery market have greater payoffs than corresponding bets placed in the bookmaker‐based market. However, the opposite is true for outcomes with relatively low payouts (that is, higher‐probability events). Results suggest that participants in the sports lottery market tend to bet more toward high‐probability events than the amount implied by the bookmaker's odds. Results also suggest that the favorite‐longshot bias is still present in the bookmaker market, even when there is less threat of privately informed bettors than in horse racing.     

金融危机下的风险管理

2008年以来,全世界都处于经济危机的漩涡之中,风险管理的缺失被认为是其中原因之一.一直以来,风险管理主要侧重于市场、信用和营运风险.对于银行机构来说,这些风险实际上已经在巴塞尔新协议中作了规范,而且都单独对这些风险进行管理和应对.     

Shopping plans,buying motivations,and return policies: impacts on product returns and purchase likelihoods

Product return behavior and factors that contribute to product returns are an under-researched area, despite significant importance to manufacturers and retailers. The current research attempts to fill the gap by focusing on two factors that shape consumer purchase behavior: (1) whether purchases are planned or unplanned, and (2) whether hedonic or utilitarian motivations drive purchases. The findings show that purchase plans and buying motivations have distinctive and interactive impacts on pre-purchase concerns, self-estimated likelihood of returning purchases, and purchase intentions with or without return policies. When hedonic motivation drives purchases, unplanned (vs. planned) purchases lead to higher return concerns, higher return likelihood, and lower buying intentions. When utilitarian motivation drives purchases, planned and unplanned purchases have comparable return concerns, return likelihood, and buying intentions. This interaction effect on buying intentions dissipates when a lenient return policy is offered.     

Leadership competency inventory: A systematic process of developing and validating a leadership competency scale

This article reports psychometric evaluation of the Penn State Leadership Competency Inventory (LCI). The 32‐item LCI was validated on a sample of 323 managers in the health care industry. Preliminary validity and reliability evidence of the LCI was established through exploratory factor analysis (EFA), item‐total correlations, Cronbach's alpha coefficients, and confirmatory factor analysis (CFA). The four‐factor leadership competency scale, comprising supervisory and managerial competencies, organizational leadership, personal mastery, and resource leadership, accounted for 58% of variance. According to CFA results, the model fit of the four latent factors of the LCI was confirmed to be appropriate. Cross‐validation with other populations is needed to confirm the factor structure. Limitations and further research recommendations are discussed.     

Abusive Supervision,Psychological Distress,and Silence: The Effects of Gender Dissimilarity Between Supervisors and Subordinates

Previous research has shed light on the detrimental effects of abusive supervision. To extend this area of research, we draw upon conservation of resources theory to propose (a) a causal relationship between abusive supervision and psychological distress, (b) a mediating role of psychological distress on the relationship between abusive supervision and employee silence, and (c) a moderating effect of the supervisor–subordinate relational context (i.e., gender dissimilarity) on the mediating effect of abusive supervision on silence. Through an experimental study (Study 1), we found the causal path linking abusive supervision and psychological distress. Results of both the experimental study and a field study (Study 2) provided evidence that psychological distress mediated the relationship between abusive supervision and silence. Lastly, we found support that this mediation effect was contingent upon the relational context in Study 2 but not in Study 1. We discuss implications for theory and practice.     

Functional-coefficient models for nonstationary time series data

This paper studies functional coefficient regression models with nonstationary time series data, allowing also for stationary covariates. A local linear fitting scheme is developed to estimate the coefficient functions. The asymptotic distributions of the estimators are obtained, showing different convergence rates for the stationary and nonstationary covariates. A two-stage approach is proposed to achieve estimation optimality in the sense of minimizing the asymptotic mean squared error. When the coefficient function is a function of a nonstationary variable, the new findings are that the asymptotic bias of its nonparametric estimator is the same as the stationary covariate case but convergence rate differs, and further, the asymptotic distribution is a mixed normal, associated with the local time of a standard Brownian motion. The asymptotic behavior at boundaries is also investigated.     

Coordinating and competing in ecosystems: How organizational forms shape new technology investments

We consider firms in the context of their business ecosystems and explore how differences in the ways in which firms are organized with respect to complementary activities affect their decision to invest in new technologies. We argue that, in addition to creating differences in incentives and bureaucratic costs, firm‐complementor organizational form plays an important role in the firm's ability to coordinate accompanying changes in complementary activities so as to shape the benefits from investing early in the new technology. We test our predictions in the U.S. healthcare industry from 1995–2006. The study makes a strong case for viewing firms' competitive strategies in the context of their business ecosystems and for the existence of an important link between firms' coordination choices and their strategic investments.

Using Twitter Data for Cruise Tourism Marketing and Research

The need to understand how social media affect the hospitality and tourism field has increased. This paper discusses and demonstrates social media analytics using Twitter data referring to cruise travel. This research also includes an in-depth analysis of tweets by three types of user groups: commercial, news/blogs, and private. The results show that not only were words related to travel, destination, industry, and emotion most frequently used in composing tweets, but celebrities, professional bloggers, cruise lines, and travel agencies actually led major subgroups on cruise topics on Twitter. Based on such findings, this study provides feasible marketing strategies.
